PReSBOX Asphalt Prism Shearbox Compactor

PReSBOX Asphalt Prism Shearbox Compactor

PReSBOX® provides the latest in asphalt specimen preparation and mix evaluation technology producing high quality asphalt prisms from which beams and cylinders with excellent air voids distribution, homogeneity and particle orientation can be cut.

The unique shearing action of the PReSBOX® closely replicates the conditions under which asphalt is placed in the field and produces specimens with excellent homogeneity and volumetric properties, giving an exceptional measure of workability.

PReSBOX® also provides an accurate measure of the workability (relative effort required for compaction) of Hot Mix Asphalt (HMA) needed in the field to achieve a target void content.

It also features a PC interface for user entry of compaction parameters, and provides a real-time graphic display of data, e.g. specimen height, vertical stress and air voids per cycle.

Features

• PReSBOX® produces a prismatic specimen with nominal dimensions of 450 mm (length) x 150 mm (width) x 120 to 185 mm (height)
• Asphalt prisms prepared in the PReSBOX® compactor can be sawn or cored to produce 4-6 prismatic beams or 1-4 cylindrical specimens.
• A single person is needed to operate PReSBOX®
• Produces specimens with excellent air void distribution and particle orientation
• Designed for an easy unlocking of the compaction mold, facilitating an effortless specimen extraction at safe height, handling and user safety.
